Who needs Vitamin K the most? NEW study on Aortic Calcification and Vitamin K2

I have had many requests to discuss vitamin  K2 and so in this video we will be answering   the following questions what does vitamin K do  and what is its role in the body who is at risk   for a vitamin K deficiency what are the signs  and symptoms of a vitamin K deficiency what are   the dietary sources of vitamin K and can vitamin K  supplements interact with medications if you stick   with me till the end I will show you a very recent  study on vitamin K2 and its role in calcification   and aortic stenosis that had some very interesting  findings before we continue I'd like to remind you   that this video is not a replacement for medical  advice please do not make any changes to your diet   or medications without speaking to your health  care provider first there is increasing evidence   that in some cases our Western diet and the way  that our food is produced may be leaving us more   prone to different nutritional deficiencies it  is true that maintaining a diet that is complete   with Whole Foods that you can cook and prepare  yourself is ideal however this is not always   the case and this is not always the situation  we know that vitamins are essential nutrients   these nutrients are essential to maintain life and  maintain many of the chemical reactions that our   body needs to produce different life-sustaining  proteins for example it is important to remember   that vitamins are divided into those that are fat  soluble and those that are water soluble the fat   soluble vitamins include vitamins a d e and K  and so Vitamin K is the vitamin that we will   be focusing on this being a fat soluble vitamin it  might be easy to confuse vitamin K with an element   called potassium these are two very different  components Vitamin K is an organic compound   whereas potassium represented by K on the periodic  table is an inorganic element so it's important to   make this distinction before we go any further  so what does vitamin K do and what is it good   for the original term for vitamin K comes from the  German word coagulation meaning the body's ability   to clot or to prevent a hemorrhage newborn babies  in particular are at higher risk for a vitamin K   deficiency and this is why when babies are born  they are quickly given a vitamin K injection in   order to help prevent any tragic outcomes from  hemorrhaging due to a vitamin K deficiency it is   important to note that our body does not store up  large quantities of vitamin K and the quantities   of vitamin K that it does store it seems to use  quite rapidly so we do need to acquire vitamin   K either from our diet or from supplementation  when we speak of vitamin K we are referring to   a group of vitamins that are necessary cofactors  for the production of many different substances   and proteins in the body these proteins are  essential for maintaining adequate coagulation in   the body as well as normal levels of calcium since  vitamin K was discovered we have learned that it   plays a very important role in disease States like  osteoporosis vascular calcification osteoarthritis   cancer and even cognition vitamins that are part  of the group of vitamin K vitamins include vitamin   K1 phyloquinone vitamin K2 menaquinone which can  be produced by gut bacteria and the little known   or lesser-known vitamin K3 which is a synthetic  vitamin that is currently being studied for   different cancer treatments and is currently  not available to the public vitamin K2 known   as menaquinone 4 and menaquinone 7 are vitamins  that are essential for the process of coagulation   in particular for the formation of the protein  prothrombin prothrombin is a protein in the body   that gets converted to thrombin when you say cut  yourself and this helps to Aid in the formation   of a blood clot without these important proteins  like prothrombin and thrombin you would not be   able to form the clots that are necessary to help  prevent bleeding in different places in the body   especially when you have a cut or another type of  injury vitamin K also helps the body to utilize   and strengthen our bones according to Mount Sinai  research has found that people who have higher   levels of vitamin K have greater bone density  while low levels of vitamin K have been found in   those with osteoporosis there are other studies  suggesting that low levels of vitamin K may put   people at greater risk for osteoarthritis there  is increasing evidence that vitamin K may help   to prevent fractures in post-menopausal women who  are at greater risk for osteoporosis we also have   evidence that vitamin K contributes to bone health  in male and female athletes and this is because   vitamin K helps to activate a protein called  osteocalcin osteocalcin plays a very important   role in bone formation and mineralization and this  helps to strengthen bones and prevent fractures   osteocalcin is the most important protein found  in bone after collagen and it is produced by   cells called osteoblasts osteocalcin also acts as  a hormone to adjust insulin and glucose levels in   the body it increases testosterone AIDS in muscle  strength and it also helps with cognitive function   let's discuss who is more at risk for developing  a vitamin K deficiency vitamin K deficiency is   fairly rare because we can acquire vitamin  K through our diets say through green leafy   vegetables or in many cases our gut is also able  to produce vitamin K those who are more at risk   for a vitamin K deficiency are usually people who  have a low amount of vitamin K in their diet diet   or they have a malabsorption issue meaning that  they are not able to absorb enough vitamin K   from their diet for their body to utilize this  includes individuals who suffer from alcohol   abuse General malnutrition malabsorption liver  gallbladder and biliary diseases celiac disease   and cystic fibrosis it's also important to note  that those who are already prone to a vitamin   K deficiency and are given long-term antibiotics  may be at risk for deficiency and this is because   the antibiotics are not selective and they can  deplete the very bacteria that are responsible   for producing vitamin K in the gut those who are  on long-term hemodialysis and those who suffer   from severe burns are also at a higher risk for  vitamin K deficiency there is also evidence that   some patients who have Alzheimer's may be at a  higher risk of vitamin K deficiency due to a lower   amount of vitamin vitamin K in the diet there is  some research that suggests that supplementation   with vitamin K in older but healthy adults  may help to improve cognitive function however   caution is warranted because supplementation  with vitamin K can interact with medications   and we will speak about this in a moment so what  are the signs that you may be deficient in vitamin   K the daily requirement for vitamin K for women  is 90 micrograms a day and 120 micrograms a day   for men though deficiency is considered to be  rare a vitamin K deficiency may present in the   following ways a prolonged Prothrombin time and  this can be measured with a very simple blood   test unusual bleeding easy bruising or gums that  are bleeding quite frequently this could also be   caused by other things but it could be a sign of  vitamin K deficiency hemorrhaging osteopenia which   is a condition where there is lower than normal  bone mass or bone density and even osteoporosis   what type of foods contain vitamin K vitamin K1  is mostly found in plants and is our main dietary   source of vitamin K whereas vitamin K2 is found in  fermented foods and some meats and cheeses foods   that contain a significant amount of vitamin  K include broccoli kale spinach asparagus and   dark green lettuce beef liver green tea and turnip  greens are also abundant in vitamin K chlorophyll   is the substance in plants that gives plants  their green color and is abundant in vitamin   K finally vitamin K can also be found in soybean  and canola oil fortified meal replacement shakes   and the menaquinones can be found in natto which  is a type of fermented soybean as well as smaller   amounts that can be found in meat cheese and eggs  it is very important to note that freezing foods   can destroy the amount of vitamin K in that food  however heating or cooking foods does not seem   to destroy vitamin K it really is not difficult  to ingest adequate amounts of vitamin K daily in   the video description below I will give you a  chart that shows you the amounts of vitamin K   found in different foods you will see that just  half a cup of beets will provide you with 368   micrograms of vitamin K so this goes back to the  importance of maintaining a healthy diet full of   Whole Foods that you can cook this ensures that  you will get enough vitamin K daily so if you are   considering supplementing vitamin k a question  you should be asking is can vitamin K interact   with medications and the answer is yes a change  in diet that results in excess intake of vitamin K   from dietary sources can interact with a group of  medications known as oral anticoagulants in this   case the medication that we are most concerned  with is Warfarin otherwise known as Coumadin   vitamin K supplements should not be taken well  on the medication warfarin however if you are   already on Warfarin and taking vitamin k please  do not make any adjustments without talking to   your primary care provider first there are  however newer medications that are being   used with increasing frequency that do not have  this type of interaction with vitamin K another   medication that can interact with Vitamin K is the  antibiotic family cephalosporins if a person is   given a cephalosporin like cephalexin or Keflex  or sepharoxine there is a whole family of these   medications for more than 10 days this could leave  someone who is already prone to deficiency to be   deficient in vitamin K we know that patients who  are given antibiotics for longer terms are more   prone to deficiency another medication that can  leave babies more prone to vitamin K deficiency   if their mothers are on this med education this  medication is called phenotoin otherwise known   as Dilantin now vitamin k does not cross the  placenta and it does not cross into breast   milk in very high amounts and mothers who are on  this medication are more prone to deficiency in   the first place meaning that their babies will get  less vitamin K from the mother and so this needs   to be monitored by a physician there is another  medication that is often used for weight loss   and it is a bile acid sequesterant that we know  as orlastat or xenical this medication helps to   reduce the amount of fat that the body is actually  absorbing in doing this it also reduces the amount   of fat soluble vitamins vitamin A d e and K that  the body is able to absorb so this could leave   someone more prone to a deficiency if used over a  long period of time now there's a very interesting   study that looked at the supplementation of  vitamin d and vitamin K versus placebo and   cardiovascular health they looked at whether this  type of supplementation could help to prevent the   progression of calcification in patients with  aortic stenosis now this was a multi-center   double-blind randomized trial it was a very high  quality study this trial looks specifically at   men who had evidence of aortic and coronary artery  calcification as verified and monitored by CT Scan   they looked at whether giving patients either a  placebo or vitamin D with vitamin K2 would help   to prevent the progression of calcification the  men were divided into two groups and given either   Placebo or 720 micrograms of menaquinone 7 plus  25 micrograms of vitamin D these patients were   then monitored over a period of 24 months  though this trial noted that there was no   significant difference in the progression rate  of calcification in those treated with vitamin D   and mk7 versus placebo they did however note that  there was a significant reduction in a particular   protein known as dephosphorylated uncarboxylated  Matrix GLA protein in the mk7 plus vitamin D group   this being a biomarker of functional vitamin K  status we do know that high plasma concentrations   of this particular protein are a reflection of  poor vitamin K status there is definitely a need   for more high quality research on the benefits  of vitamin K2 supplementation fortunately for   most healthy adults we know that dietary intake of  vitamin K2 is quite easily attainable though some   vitamin D supplements are already coming with the  addition of vitamin K2 it's particularly important   to ask your healthcare provider before taking  any of these supplements in particular if you are   already taking other medications or  supplements that could interact this   will also give you information as to when you  should take the medication so you can properly   absorb this and get the most benefit from your  vitamins and supplements if you like this video   don't
